Treeview in ComboBox selectedvalue empty

[Roy]

When a node of the treeview (in a combobox) is clicked, the text and value of this node is set to the selected item of the combobox. client side this works well. serverside the selectedvalue is rondomly empty.

function nodeClicking(sender, args) {

 

 

var comboBox = $find("<%= cbEmployees.ClientID %>");

 

 

var node = args.get_node()

 

comboBox.set_text(node.get_text());

comboBox.trackChanges();

 

var item = comboBox.get_items().getItem(0);

 

item.set_value(node.get_value());

item.set_text(node.get_text());

comboBox.commitChanges();

comboBox.hideDropDown();

comboBox.attachDropDown();

}

Hello Roy,

Here in this scenario the SelectedIndexChangedEvent won't fire because there is only one item that is TreeView and one approach is to access the comboboxtext that you set from the clientside.
JS:

<script type="text/javascript">
function nodeClicking(sender, args)
{
  var comboBox = $find("<%= cbEmployees.ClientID %>");
  var node = args.get_node()
  comboBox.set_text(node.get_text());
  comboBox.trackChanges();
  comboBox.get_items().getItem(0).set_text(node.get_text());
  comboBox.commitChanges();
  comboBox.hideDropDown();
}
</script>

C#:

protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = "You selected " + cbEmployees.Text;
    }

Thanks,
Shinu.
